pQTLtools: A reference manual

In jinghuazhao/pQTLtools: A Protein Quantitative Trait Locus Toolkit

A reference manual

Description

It seeds the following collection of data and utilities for pQTL analysis: 1. Articles linking functions for cis/trans classification, pQTL-gene plot, 2d/3d-plotly plots, forest plots among others available from gap, https://cran.r-project.org/package=gap; 2. Query on genes, regions, and SNPs via PhenoScanner, https://github.com/phenoscanner, adding functionality for pQTL novelty check; 3. Downstream analysis such as colocalization, pQTL-Mendelian Randomization via TwoSampleMR. https://mrcieu.github.io/TwoSampleMR/, mapping of UniProt IDs to other resources; 4. Bioconductor notes, and showcases of LocusZoom.js snakemake workflow.
